Looks like Timo is right. Thanks for providing the links to the photos Timo! The interesting thing is that these types of halberds have poles which are round in cross section. The Germanic halberds that Iím more familiar with tend to have edged cross section to prevent slipping and twisting in the hands. The languets of the halberd are also designed to fit round cross section poles whereas the Germanic ones typically have flat languets rather than rounded. By the 18thC halberds can be assumed to have largely ceremonial uses so itís interesting that kronckew notes that his halberd blade is sharpened. You would tend not to sharpen purely ceremonial weapons to reduce the possibility of accidents, so the intention of practical use seems to be present with this piece.
